Yes. Aquamacs uses frames for special purposes intensively, you could
take example on the code there.

I would add a find-file-hook and test for these specific files, and in
the hook set the frame as I want. For merely one file, I wouldn't
use another emacs instances (though there's one parameter that cannot
be made different in different frames: the frame border use the same
face on all frames). Only for a process, since emacs isn't threaded,
a long operation in a process can freeze emacs for some time, so I may
use a different emacs for erc and gnus. If you use a different emacs,
you need to use the window manager to focus on one emacs or another,
while with a single emacs, you can focus to another frame with C-x 5
o. But of course, if you use ratpoison, it can be workable, since
then you can just type C-t o.

Probably. Have you tried man emacs or emacs --help?
What I do, when I want to launch special purpose emacsen, is:
alias special-purpose='emacs --eval "(my-special-purpose-function)"'
and I set the defaults specially in my-special-purpose-function,
loaded from my normal '~/.emacs'.
I prefer to keep one .emacs (even across different systems!), and test
inside it for the special circumstances, using these variables and
others:
;; system-type darwin gnu/linux cygwin
;; system-name "naiad.informatimago.com" "host.example.com"
;; system-configuration "i686-pc-linux-gnu" "i686-pc-cygwin"
;; window-system nil x mac w32
;; emacs-major-version 18 19 20 21
;; emacs-minor-version 0 1 2 3
;; emacs-version "20.7.2" "21.2.1"
